Excited-state magnetic properties of carbon-like
Lukas J. Spieß, Shuying Chen, Alexander Wilzewski +13
We measured the -factor of the excited state in ion to be with a relative uncertainty of . The magnetic field…
Resonant photon scattering in the presence of external fields and its applications for the Gamma Factory
Jan Richter, Mieczyslaw Witold Krasny, Jan Gilles +1
This theoretical study explores resonant elastic photon scattering in the presence of external electric and magnetic fields, motivated by potential applications in storage ring exp…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
Quadratic Zeeman and Electric Quadrupole Shifts in Highly Charged Ions
Jan Gilles, Stephan Fritzsche, Lukas J. Spieß +2
Recent advances in high-precision spectroscopy of highly charged ions necessitate an understanding of energy shifts of ionic levels caused by external electric and magnetic fields.…
